This module lets one create one or more redundancy descriptors, which then may be applied to a set of files distributed across a group of processes.
Usage is documented in src/redset.h, doc/rst/redset.rst, and the User API docs. Also see the example program in the test directory.
Implementation details can be found in doc/rst/implementation.rst and doc/rst/schemes.rst.
To build dependencies:
git clone git@github.com:ECP-VeloC/KVTree.git KVTree.git
git clone git@github.com:ECP-VeloC/rankstr.git rankstr.git
mkdir install
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=../install -DMPI=ON ../KVTree.git
make clean

make install
make test
cd ..
rm -rf build
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=../install -DMPI=ON ../rankstr.git

To build redset:
cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=./install -DWITH_KVTREE_PREFIX=`pwd`/install -DWITH_RANKSTR_PREFIX=`pwd`/install .

make install
Some simple test programs exist in the test directory.
